摘　　要：测得了二氨基呋咱(DAF),二硝基呋咱(DNF)及二氨基偶氮呋咱(DAAzF)的燃烧能和比热容。三种化合物的燃烧能分别为(-13043±119),(-6863±37)和(12661±54)J·g^(-1),同时,计算得到了基于不同燃烧产物的标准摩尔生成焓(Δ_fH_m~Θ)。三种化合物298.15K时的标准摩尔热容分别为(140.8±0.1),(236.8±0.2),(216.9±0.2)J·mol^(-1)·K^(-1)。燃烧能随着分子中氧含量的增加而减少(DAF>DAAzF>DNF)。氨基基团有助于提高燃烧能,硝基则有负作用。对于比热容而言,三种化合物的变化规律与燃烧能相反。Abstract： Energies of combustion and specific heat capacities of diarninofurazan （ DAE）, dinitrofurazan （DNF） and diaminoazofurazan （DAAzF） were determined. Energies of combustion for the three compounds are （ -13043±119）, （ -6863 ±37） J · g^-1 and （ -12661 ±54） J · g^-1 , respectively. The corresponding standard molar enthaIpies of formation （ΔfHm^Θ） were obtained with the different combustion products. The values of specific heat capacities for the three compounds are （140.8±0.1）, （236.8±0.2）, （216.9±0.2） J·mol^-1·K^-1, respectively. Energy of combustion tends to rise with the decrease of oxygen content in molecule （DAF〉DAAzF〉DNF）. Amino group contributes to increase energy of combustion, but nitro group has the opposite effect. As for the specific heat capacity, the change rule is opposite to energy of combustion.
